Micro stuttering

[el-nino]

Hi all looking for a little help. I'm getting quite bad micro stuttering in high end games, bf2042, hitman 3, rdr2, dying light 2 etc.

Running i9 9900k @5ghz 32gb ram @3200 zotac 3090 Samsung 970 m.2 z390 aorus master

All temps are fine I'm not seeing any thermal throttling through hardware monitoring I even did a fresh install of Windows and drivers but issue persists. Frame rates look decent usually between 60 to 120 in these titles at 3840x1600p. But I 99 percentile drops as low as 27.

I have seen other 3090 and 3080/ti owners complaining of same issues on other manufacturers cards wondering if anyone had any idea?

I was considering a 12000k but was going to hold off for the AMD next Gen

I believe I've found the issue. Turns out my PCIe 3.0 slot is running at PCIe 2 speeds. I'm going to remove one of my m.2 drives today to test.

Hopefully it is that simple but if not use something like Process Explorer to see what is running in the background - could be a maintenance task or similar taking up CPU time. Monitor DPC latency to see if there is a driver flaking out, etc. if you are overclocking RAM try removing the overclock as sometimes RAM can appear to be stable but still cause stutter and/or try other timings/frequency as sometimes a specific combination of hardware/software with certain RAM settings just doesn't seem to be smooth for whatever reason.

Thank you and all of you that replied
